To all 'whom it may concern:

Be it known that I, HENRY A. ALLwAnnT, a citizen of the United' States, residingat Battle Creek, in the'county of Calhoun, State of Michigan, have invented certain new and useful Improvements in Bottle-Capping Machines; and I do declarethe following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the gures of reference marked thereon, which form a part of this specification.

This invention relates to a bottle capping set forth and claims.

The object of the invention is to provide a pointed out particularly inthe v machine of the' character described, of comparatively simple and inexpensive construction, wherein the arrangement is such as to enable a filled bottle tobe readily and perfectly capped orcrowned so as to seal the contents therein, provision being made for feeding the caps successively into position 'I to be crimped onto the 4heads of the bottles.

The above robject is attained by the structure illustrated in the accompanying drawings, in which Figure 1 is a view partly in section, of a -machine embodying my invention, showing. thereon a bottle in position for capping.

L. Referring to the characters of reference, 1

"designates a suitable frame in the lower part of which is j ournaled a main shaft 2 adapted to be driven by a belt pulley 3 thereon from any suitable source of power.

Upon the shaft 2 is a cam 4 having a high point Rolling upon the cam 4 is an antifriction roller journaled in the lower end Aof a vertically reciprocatory shaft 7 which -ble spring 10 which is confined between the collar 11 onthe lower section, and the collar 12 on the upper section. Said spring normally maintains said sections in proper relation but will yield to permit one of the sections to enter the other during the up' ward movement of said shaft should the u ward travel of the disk 9 be resisted, o viating the possible breaking of a bottle carried on said disk.

Secured at their lower ends in the top 13 of the frame and projecting vertically therefrom are the rods 14 which carry at their upper ends the capping head 15 having a vertical aperture 16 therethrough adapted to receive the head 17 and neck 18 of a bottle 19. Within the lower portion of said head 15 and surrounding 'the aperture there. through is a compressible collar 20 adapted to bear against the neck of the bottle to guide it in its vertical movement. In the upper end of the aperture 16, through said head is a tapered steel ring 21 of such shape as to crimp the caps onto the heads of the bottles when forced upwardly into said aperture, as hereinafter explained.

Surrounding the central Vaperture 16 through the head 15 is an annular channel 22 into which depends the circular ange 23 on the reciprocatory cross head 24 supported above the capping head 15 in working relation therewith. Depending centrally from the cross head 24 Within the circular ange 23 thereof is a cylindrical block 25 adapted to enter the opening through'the tapered roo ring 21 andvr to extend within the opening 16 through the head 15. Said cylindrical block serves as an abutment for the crowns or caps 26 to force them onto the heads of the bottles over the mouths thereof as the neck of the bottle is carried. upwardly into the stationary-head 15. Connected to the opposite ends of the cross head 24 are. the vertically reciprocatory rods 27 which pass through the top 13 of the frame and through the cross` bar 8, said rods carrying at their lower ends the an'tifriction rollers 28 which rollin peripheral Contact with the cams '29' onthe main shaft 2. Embracing the rods 27 and confined between the collars 30 thereon and the top of t-hev frame are the compressible springs 31 which return the rods 27'after they have 'been raised' vertically by the cams 29.

The crowns or caps 26 are contained in a hopper32 from which leads a spout 33 down which said crowns are fed to a way formed in the capping head 15 and communicating with the aperture 16 therethrough.v4 Adapt- 'ed to reciprocate in said way is a slide 34 .whose forward end is adapted t-o engage the crowns to slide them into position for capping4 the bottles, and whose rear end is supported in a bracket 35 mounted on -the arm 36 of the frame. Attached to the rear end of the slide 34l are the coiled springs 37 which return said slide after each forward movement thereof to feed a cap into the capping head 15, said springs being connected to said slide through the medium of the laterally projecting pins 38 on the rear end said plate.

thereofvto which the forward ends of said springs are attached. Formed through the slide 34 is a longitudinally extending slot 39.

a Iiying uponthe'slide 34 and adapted to reciprocate thereon is av plate 40 having a longitudinal slot 41 therethrough, said plate being confined to said slide and directed in its movement thereon by means of the pins 42 mounted in said slide which pass through the parallel longitudinally extending slots 43 in Extending laterally from the forward end of the plate are the pins 44 to which are attached the forward ends of the springs 45, the rear ends of said springs beingsattached to the pins 38 on the slide 40. .The tension of the springs 45 is greater than that Aof the springs 37.

The slide' 34 is actuated to feed the crowns or caps into the capping head by means of a vertically reciprocatory rod 46 which asses through the registering slots in the sllde 34 and theplate 40, and is provided near its upper end with a cam 47. The positionof the cam 47 upon the rod-46is such that as said rod moves downwardly, the inclined face of said cam will engagethe plate 40 at etL l slide.

head 15, as clearly 'shownin Fig. 5. Upon an' upward or Vreturn movement of the rod l46',- the springs 37 will return the slide and' plate to their normal positions. Should the Acaps become clogged in the way through which they are fed to the. capping chamber in the head 15., froxn the spout 33, a downward movement of the rod 46 `under such condi-- `tions willnot actuate the slide 34, for the an travel of said lslide, and allow the plate 40 only to be actuated by the downward movement ofthe cam 47, thereby obviating the breaking of the parts through the cloggin'g/ of the machine. cap is displaced and carried intovthe capping chamber through the actuation of the slide 34,.the` superimposed caps in the spout 33 are supported' upon ysaid slide, and that the lowermost of said caps will drop into position to be carried into the capping chamber, as the slide is withdrawn from under the spout upon its rearward or return move- 'ment A Motion is imparted to the rod 46 to actuate lthe feeding'slide, through the medium 'of a lever 48 which is piv'oted to the lower end of the rod 4 6 and is engaged by a cam 49 o n the shaft 2. Said cam is so positioned upon said shaft as to depress the lever 48 and draw downwardly upon the rod 46 to feed a cap into the capping chamber at the proper time in the operation of the machine.

reason that the springs 45 will yield when g undue resistance is offered to theA It will be noted that as .a

In the actuating rod 46 is an expansible'4 joint consisting of acylindrical case 50 in which the upper portion of said rod carrying the annular disk 51 is conlined and adapted to move vertically, as clearly shown Oin Fig. 7. Surrounding the rod andconfined between said disk andv the end 52 lof said case is a compressible spring 53. This expansible joint overcomes the rigidity of the connection between the lever andthe cani 47, and permits the lower portion of said rod to be actuated without operatingv the upper portion carrying the cam should any injury to the parts interfere with the movement of the cam 47 'in its vertical travel.D

kIn the operation of the machine, the bottles which are filled are placed upon vthe supporting disk 9, which as it rises vertically through the operation of the shaft 7, causes the head ofthe bottle to enter the capping chamber inthe head 15. Asthe head of the bottle enters said chamber, it encounters the cap 26 supported therein and carries said cap upwardly against thecylindrical block 25 of the' cross head 24, whereby the cap is forced ontothe head ofthe bottle. At this moment in the operation of the ma? chine, the head 24 rises through the operation ofthe cams29 andthe .bottle is moved f return movement of the shaft 7 the bottle isr withdrawn from the capping head, at which time the lever 48 is depressed to actuate the rod 46 and caiise the cam 47 to move the slide 34 forward to feed a succeeding cap into position in the capping head. Another filled bottle is then placed in position upon the supporting disk 9 and the operationof capping repeated.

To return the rod 46 after it is depressed by the cam 49, a coiled spring 54 is employed which is confined between the 55 on the frame through which saidD rod passes and the`fixed collar 56 on said rod..

The rod 46 is supported at its upper endby a guide 57 through which it passes.

l The caps in the hopper 32 are fed into the spout 33 by suitable devices, Within said hopper, not shown, actuated by the shaft 58 passing therethrough, and driven by the vertical shaft 59 from thev main shaft 2 through the medium of the beveled gears 60.
